Abstract

Laser Doppler Anemometers provides a non-intrusive means for carrying out flow studies. The problems associated with obtaining coherent readings in a glass-sided open water channel with supercritical pseudo fully-developed flow are discussed. An unusual velocity distribution has been found. The aim was to verify that the data obtained in the shear flow adjacent to specimen ship plates coated with a well-known ablative paint, used in shipping industry, mounted along the bed of an open flume water channel, satisfy the general similarity laws, governing turbulent boundary layers. Comparison was made with the well-known logarithmic law, applicable to both smooth and rough surfaces, from which the surface friction characteristics were deduced.
